Title: Improvements in or relating to treatment of polymerised chloroprene
IPC: C08C3/02
Filed: 1935-11-30
Abstract: Polymerized chloroprene is freed from malodorous impurities by exposing the material in rubbery condition and having a large surface compared with its mass, to the action of a selective solvent for the impurities.  Suitable solvents are aliphatic monohydric alcohols, saturated and unsaturated aliphatic hydrocarbons, ethers, naphtha, and saturated cyclic hydrocarbons, but preferably an alcohol such as methyl, ethyl, propyl or butyl alcohols.  In examples, the material sold under the Registered Trade Mark " Duprene " is (1) formed into a sheet \ba1/32\be of an inch thick and treated in a rotary drum with ethyl alcohol; (2) formed into a sheet \ba1/4\be inch thick and ground in a ball-mill together with solid carbon dioxide, the finely-divided material being then allowed to reach room temperature and extracted with a solvent such as ethyl alcohol; (3) formed into a sheet \ba1/32\be inch thick, cut up into small pieces, and placed in a wire cage which is rotated in a drum containing ethyl alcohol; (4) milled on rolls and treated with ethyl alcohol; for instance, the material issuing from the rolls may pass into the alcohol and back to the rolls, or ethyl alcohol may be directed on to the material as it passes through the rolls, or the rolls may be submerged in ethyl alcohol.  When the initial material contains a stabilizer such as a phenyl naphthylamine which is removed by the solvent treatment, this may be added subsequently.  Where a solvent such as naphtha is used which swells the material, excess solvent may be removed for instance by pressing or centrifuging. Specification 387,363 is referred to. The Specification as open to inspection under Sect. 91 includes the treatment of polymerized haloprene.  This subject - matter does not appear in the Specification as accepted.

Title: Telegraph synchronizing system
IPC: H04L7/00
Filed: 1922-12-06
Abstract: 209,573. Murray, D. Dec. 6, 1922. Multiplex telegraphs; synchronous movements. -In a multiplex printing telegraph system in which synchronism is obtained by correction by the message signals or signals substituted therefor, such substituted signals are produced and correct phase relation is attained by using permanently reversed polarity on one channel only of the multiplex. The correction may be effected by the use of interfering contacts in known manner to control the speed of the receiving mechanism. For this purpose, the back and front contacts 11 of a correcting relay 10 operated by the arriving signals may be arranged to interfere with a contact 13 of a reed V<2> controlling the phonic wheel 17 at the receiving station, these contacts being in the circuit of the vibrator magnet 9 controlling the reed. At the transmitting station, the five contact levers corresponding to channel A rest normally against their marking contacts while those corresponding to channels B, C, D rest normally against their spacing contacts, and at the receiving station the channel A printer operates normally on the back contact 5 of the recording relay 6. The natural rate of vibration of the reed V<2> is adjusted to be about 0.2 per cent faster than the rate of arrival of the signals. To obtain correct phase relation, the transmitters are stopped, and a device is operated manually to transfer the actuation of channel A printer temporarily to the front contact of the relay 6 while shortcircuiting simultaneously the contacts 11, thus causing a five-unit marking signal to travel around the receiving distributor. The transmitting and receiving distributors are in correct phase relation when this signal is recorded correctly by channel A printer, whereupon a lever is automatically selected in the printer and is moved into position to open contacts 28 or to release a mechanical device to place the contacts 11 again in circuit and to restore the actuation of channel A printer to the back contact of the relay 6. In the arrangement shown in Fig. 1, the parts are set for automatic phase-finding by operating a hand-lever 18 against a spring to close a holding circuit through magnets 19 and 21 an'd the contacts 28, the magnet 19 moving a lever 20 to transfer the actuation of channel A printer to the front contact of the relay 6, and the magnet 21 moving a lever 23 against a contact 24 to short-circuit the contacts 11. In another arrangement a button on a sliding rod is manually pressed until a hook on the rod is engaged by a spring pawl, the levers 20, 23 being actuated simultaneously, and the lever selected in the printer moves to disengage the pawl when the correct phase is attained.
